Science Teaching Materials Based on Marine Aquaculture Bioecology Using Floating Net Cage Technology to Improve Science Literacy Skills for Middle School Students in Coastal Lombok

Abstract

This research aimed to develop science teaching materials based on marine aquaculture bioecology using floating net cage technology that is practical and effective in improving students’ scientific literacy skills at Lombok coastal schools. This was development research based on the Thiagarajan 4D model, which consists of four stages: design, define, develop, and disseminate. The research subjects consisted of six junior high schools on the coast of Lombok, who were selected using the purposive sampling technique. The instrument used was a scientific literacy assessment of 16 reasoned multiple choice questions. Data were analyzed using normalized gain analysis. The results showed that science teaching materials based on marine aquaculture bioecology with floating net cage technology were effective in increasing the scientific literacy skills of students in the six sampled schools, obtaining an average N-gain value of 0.5 in the medium category. Keywords: marine aquaculture, bioecology, scientific literacy skills
